The notion of lime has several uses. When it comes from the Hispanic Arabic lima (in turn derived from līmah ), the term refers to the fruit of the lime tree .
This tree , which belongs to the Rutaceae family group, is native to Persia and can reach a height of up to five meters. The lime, its fruit, is small , with an intense aroma and green color.
Limes are very acidic. That is why its juice is usually consumed sweetened with sugar . The lime peel, meanwhile, is grated and used in baking to flavor various preparations.
If the concept of file comes from the Latin lima , however, it refers to an instrument used to smooth and abrade hard surfaces . It is a steel tool with grooves in one or two directions.
With the file it is possible to polish metals and other materials. What you do is rub the teeth of the file, which has a handle or grip in its posterior sector, against what you intend to wear down or refine.
There are jewelry files , nail files , metal files and other types of files. The characteristics of each one vary depending on their purpose.
The cost of the metal file is relatively low but it is a very useful tool for shaping and smoothing metal or hard plastic surfaces with great precision. Additionally, it lasts for many years before deteriorating significantly. With it, cross and transversal filing is possible, in addition to surface maintenance.
Once we have the right file for the type of material we need to work on, it is recommended to plan the task and make marks in the areas we need to smooth, for example. We must make sure that the file is harder than the surface so that it does not get damaged. Similarly, we should not use diamond-encrusted files to treat smooth surfaces, to avoid scratching the diamonds.
Before each session, it is important to clean the file to remove any remains of previous work, as well as any dust that has collected between your teeth . If the dirt is difficult to remove, we can help ourselves with a hard-bristled brush or any other tool that helps us leave the file "like new."
If we want to reduce friction in order to make filing smoother, we can apply oil or butter on the file. This also greatly reduces the volume of metal dust released; As a result, the environment is less harmful to our lungs and subsequent cleaning of the file becomes easier. As if that were not enough, these products also protect the tool and the object against rust.
Another trick to keep the file from clogging easily is to rub its teeth with a piece of chalk . The object to be filed must be very firm, for which it is usually attached to a work table; If it vibrates during the filing process, the result will not be very good.
Work with a cross file to remove excess material. A cross file , on the other hand, is a good option to achieve a good finish. It is common to alternate between these two techniques on the same object.
Lima is also the name of several cities and other administrative divisions. The best known is the capital of Peru , a town that develops next to the Pacific Ocean .
Lima , finally, is a fairly common surname in Latin America . A Uruguayan singer and poet, a Dominican baseball player and a Brazilian model , to name a few cases, have the last name Lima .
